Hey guys! I played today with my SLG and it seems that the seer isn't catching the bolt correctly. It shot fine before and all of a sudden, this started. What could the problem be???

well the sear may be worn and might need to be replaced, or the same for the sear spring. That or the breach may need to be re honed, DYE had to drill out my breach or something like that so you might want to send that in.

To start turn up your velocity to see if that helps. If not look below for more help.
Take apart the gun to the point where you have the breech and grip frame separated. Look on the breech and there will be a silver pin inside the sear sticking out of the bottom of the breech. Push the pin out and the sear will pop out. then look at the hook like end of the sear and see if it is worn down if not take your sear spring and stretch it a little so it will catch or buy a new one.
